PHOENIX, Ariz. — Arizona wakes this Wednesday to a sky painted clear and still, with a light desert breeze and dawn temperatures near 60 degrees. The air feels crisp before the sun quickly warms the Valley toward another near-90-degree afternoon, one of the last of this late-fall stretch before a gentle cooldown arrives by the weekend.

According to the National Weather Service in Phoenix, dry high pressure remains locked over the region through Friday, keeping skies sunny and travel conditions ideal across I-10, Loop 101, and I-17. East winds around 5 mph will stay light, helping outdoor work and early Veterans Day event setups stay on track. By Friday evening, a subtle dip in desert warmth begins as cooler air edges south from the Great Basin.

Residents should expect overnight lows to settle into the upper 50s by Saturday morning, ideal for late-fall yardwork, early Christmas light prep, or weekend hikes before next week’s chill sets in. No rain or frost risk is expected, though morning temperatures will feel noticeably cooler for early commuters and runners by Sunday.

The broader U.S. pattern turns sharply colder next week, with Arctic air pushing south from the Plains toward the Mississippi Valley by Veterans Day. Phoenix will stay dry, but travelers heading east should watch for icy travel and snow chances building from the Midwest to New England as November deepens. For now, Arizona holds its quiet, golden run of sunshine — perfect weather for a short breather before the first true taste of winter spreads nationwide.
